Service Overview

EMSA detects protein-nucleic acid interactions with qualitative and quantitative analysis and is a classic method for transcription factor research. Common formats include validation EMSA (mutant probes confirm the binding site), competitive EMSA (cold probe competition rules out false positives), and supershift EMSA (antibody recognition forms a ternary complex to confirm specific binding).

Service Advantages

  • Directly detects protein-nucleic acid interactions with qualitative and quantitative information.
  • Studies specific, non-specific, and sequence-specific interactions.
  • Technically straightforward and relatively easy to perform.
  • Adaptable through various labeling and detection methods to different experimental needs.
